29650	Model.refresh_from_db() no longer refreshes related objects	Thomas Berdy	nobody	"After updating to Django 2.1 from Django 2.0.7, I noticed one of my tests failed. After further investigation, I figured out the problem was coming from **refresh_from_db** method. Here is my test:

{{{
    s = MyCustomSerializer()
    order = s.create(copy.deepcopy(order_data))

    # Check shipping_address exists
    assert order.shipping_address

    order_data[""shipping_address""][""city""] = ""Sevran""
    s.update(order, copy.deepcopy(order_data))
    order.refresh_from_db()

    # Check order's shipping_address has been updated
    assert order.shipping_address.city == ""Sevran""
}}}

Here you can find the definition (light version) of the Order model:

{{{
class Order(TimeStampedModel):
    shipping_address = models.ForeignKey(
        ""order.ShippingAddress"", null=True, blank=True,
        verbose_name=_(""Shipping Address""), on_delete=models.SET_NULL
    )
}}}

Before 2.1, **refresh_from_db** refresh the whole object and the objects linked by foreign key. 
Now it seems that only the first-level object is refreshed.
Is it normal ? Maybe you can mention it in the release notes.
